摘　　要：结合200 t万能液压试验机的特点,按试验装置主要功能需求和使用方式进行系统设计,开发一套超低温环境力学试验装置。现场测试结果表明,该装置完全具备在室温至-196℃环境温度范围内对混凝土抗压性能和钢筋拉伸性能进行一体化准确测试能力,能够满足在低温环境开展材料力学性能试验研究工作及低温工程技术服务的需要,具有很好的应用前景。In combination with the characteristics of 200 tons hydraulic universal testing machine,we develop a set of device for testing mechanical properties of building materials at cryogenic temperature. The test results show that the device have the function of testing the compressive property of concrete and tensile property of steel bar from room temperature to- 196℃ accurately. The device has a good prospect of application which can meet to carry out mechanical testing research work at low temperatures and Technical Services of Cryogenic Engineering.
